Implementación de herramientas lean manufacturing para mejoramiento del proceso en la línea de producción de asientos en CORPMEGABUSS CIA. LTDA

Abstract

The company CORPMEGABUSS CIA. LTDA. is responsible for the manufacture and assembly of interprovincial and inter-cantonal buses. Consequently, the production of seats is conducted under stringent quality and comfort standards. Nonetheless, the company faces the issue of not meeting the one-week production deadline set by management, due to various factors identified in the analysis. Therefore, this research aimed to implement Lean Manufacturing tools to enhance the seat production line process at CORPMEGABUSS CIA. LTDA. The methodology employed was both explanatory and quantitative, involving the analysis of various indicators such as takt time, lead time, and productivity about time. These indicators were applied within the frameworks of the Kaizen and 5S methodologies to assess the current situation and subsequently establish improvements. The goal was to fulfill the requirements of both management and the involved personnel. The application of these methodologies revealed a lack of awareness among the staff regarding continuous improvement and the implemented methodologies. Consequently, the developments before and after the intervention were communicated, resulting in a 23.45% reduction in production times in the seat manufacturing area. This achievement aligned with the objectives set by management, ensuring satisfaction for both external and internal customers. Additionally, installed capacity increased by 31.42%. These outcomes were critical indicators of productivity enhancement. In this context, the standardization of the 3S was implemented through control records that demonstrated compliance, targeting group leaders and operational staff.
